AKT/PKB Kinase (Human) Assay/Inhibitor Screening Kit is a single-site, non-quantitative immunoassay for AKT activity. Plates are pre-coated with "AKTide-2T" (10), which can be efficiently phosphorylated by AKT1, 2 and 3 on a microtiter plate. The detector antibody is AT-3E2, an antibody that specifically detects only the phosphorylated "AKTide-2T".
